A helicopter police uses a flare to sear

Montfermeil, FRANCE: A helicopter police uses a flare to search for demonstrators during clashes between Police and residents, in Montfermeil, Northern Paris, 28 October 2006. Thousands of extra police moved into the Paris suburbs amid new attacks on public buses, as the restive communities marked the anniversary of the death of two teenagers a year ago which sparked riots and France's most serious social crisis in decades. In the town of Blanc-Mesnil, in the violence-prone Seine Saint Denis region, masked people attacked two public buses, setting them alight, bringing to six the number of such incidents in France since Wednesday.
